1. Set Up a Clear Incident Response Team

Setting up a clear incident response team is key for handling cyber attacks well. This means picking team members, giving them jobs, and deciding how they'll talk to each other and make choices. A good team structure makes sure all parts of dealing with an attack are covered, from finding it to fixing it.

The team should have people from different parts of the company, like IT, security, legal, and PR. Each person should know what they need to do and what others on the team do. This helps everyone work together when there's an attack.

Here are the main roles to have on your incident response team:

Role	Job
Team Leader	Runs the whole process and makes sure everyone works well together
Security Expert	Finds and studies attacks, and helps stop future ones
PR Person	Talks to workers, customers, and news people about what's happening
Lawyer	Makes sure the team follows the law when dealing with attacks

2. Create a Clear System for Sorting Incidents

Having a clear system for sorting incidents is key for dealing with them well. This system helps group incidents based on how bad they are, what they affect, and what type they are. This lets companies focus on the most important problems first. A good sorting system helps the response team quickly see how serious an incident is and act the right way.

A good incident sorting system usually has different levels, like Low, Medium, High, and Critical. Each level has its own rules, such as:

How much it affects the business
How many users it impacts
How much money it might cost

Here's an example of how to sort incidents:

Level	What it Means
Critical	Big money loss or damage to company name
High	Big impact on work, many users affected
Medium	Some impact on work, some users affected
Low	Small impact on work, few users affected

Having a clear way to sort incidents helps companies:

Deal with the most important problems first
Use their people and tools in the best way
Tell others about the incident clearly
Make specific plans for each type of problem
Keep getting better at handling incidents

3. Use Good Tools to Find and Watch for Problems

To handle cyber attacks well, you need to find them quickly. Using good tools to spot and keep an eye on possible threats is key. This helps you find problems fast and limit how much damage they can do.

SIEM and EDR Tools

SIEM

Two main types of tools are useful:

Security Information and Event Management (SIEM) systems
Endpoint Detection and Response (EDR) solutions

Tool	What it does
SIEM	Collects and checks log data from many places
EDR	Watches endpoint activities for threats

These tools help you see what's happening and act fast if there's a problem.

Always Watching

It's important to always be on the lookout for threats. This means:

Checking system logs often
Looking at network traffic
Watching endpoint activities

By doing this, you can spot odd things quickly and stop attacks before they cause too much trouble.

Working with Your Plan

Make sure your watching tools work well with your incident response plan. This helps your team:

Find problems fast
Stop attacks from spreading
Act quickly to fix issues

When your tools and plan work together, you can handle cyber attacks better and keep your company safer.

4. Create Detailed Response Procedures

Making clear steps for dealing with problems is key to a good incident response plan. These steps should cover finding the issue, stopping it from spreading, fixing it, getting back to normal, and learning from what happened.

Identify the Incident

First, you need to know when something's wrong. This means:

Watching your systems and networks
Looking for odd things like strange login tries or unexpected changes

Contain the Incident

Once you find a problem, stop it from getting worse. You might need to:

Cut off affected systems
Turn off some services
Limit access to important data

Fix the Incident

After stopping the spread, fix the main cause. This could mean:

Getting rid of harmful software
Fixing weak spots in your system
Adding new safety measures

Recover from the Incident

Now, get things back to normal:

Turn systems back on
Bring back saved data
Tell people who were affected

Learn from the Incident

Lastly, look at what happened and how you handled it:

Write down what occurred
Talk about how to do better next time
Make changes to stop similar problems

Step	What to Do
1. Identify	Watch for odd activity
2. Contain	Stop the problem from spreading
3. Fix	Remove the cause of the problem
4. Recover	Get systems working again
5. Learn	Write it down and plan for next time

5. Set Up Clear Ways to Talk During Problems

When dealing with cyber attacks, it's important to have clear ways to talk to everyone involved. This helps avoid mix-ups, keeps people updated, and makes sure everyone knows what's going on.

Know Who Needs to Know

Make a list of all the people who need to be told when there's a problem. This includes:

People in your company
Customers
Partners
Outside groups (like the police)

Decide how you'll talk to each group.

Choose Who Does the Talking

Pick people for these jobs:

Job	What They Do
Main person in charge	Leads the team dealing with the problem
Message sender	Makes sure everyone gets the right info
Expert	Knows a lot about the problem and can explain it

Make sure everyone knows their job and how to talk to others.

Set Up Ways to Talk

Have special ways to talk during problems, like:

Computer programs for dealing with attacks
Email
Chat apps
Phone numbers

Make sure everyone knows how to use these and keep them up to date.

Write Clear Messages

Make message templates for different kinds of problems. These should include:

Telling people about the problem
Giving updates
Saying when the problem is fixed

Keep your messages clear, honest, and quick.

Type of Message	What to Include
First alert	What happened, who's affected, what to do now
Updates	What's being done, when to expect more news
Problem solved	What was fixed, what to do next

6. Regularly Test and Update the Plan

Testing and updating your incident response plan often helps make sure it works well when you need it. This means trying out fake problems to find weak spots and make the plan better.

Do Practice Runs

Set up practice runs where you pretend there's a security problem, like someone trying to steal data or lock up your computers. Do these at least once a year, or when your company changes in big ways. This helps your team get ready for real problems.

When to Do Practice Runs
Once a year
After big company changes
When you get new security tools

Find and Fix Problems

During these practice runs, look for things that don't work well in your plan. You might find:

Steps that aren't clear
Not enough people or tools
Confusion about who does what

After you find these issues, fix them. This could mean changing your plan, teaching your team more, or getting new tools.

Look at Results and Make Changes

After each practice run:

Write down what happened
Talk about what went well and what didn't
Change your plan to make it better

This helps keep your plan up-to-date and ready for new types of security threats.

Steps to Improve Your Plan
Write down practice results
Discuss good and bad points
Update the plan
Get new tools if needed

7. Follow Laws and Rules for Incident Response

When dealing with cyber attacks, companies must follow certain laws and rules. These laws tell companies what they must do when there's a problem.

Telling People About Problems

If someone steals data, companies must tell:

The right government offices
The people whose data was stolen

For example, in Europe, companies must tell the government within 3 days of finding out about the problem. They must also tell people quickly if the stolen data could hurt them.

Knowing What the Law Says

Companies need to know what laws apply to them. Different laws might apply based on:

What kind of business they run
Where they work
What kind of data they have

Not following these laws can lead to big fines or other problems.

Doing Things Right

To make sure they follow the laws, companies should:

What to Do	Why It's Important
Make a good plan	Helps handle problems the right way
Test the plan often	Makes sure the plan still works
Teach workers what to do	Everyone knows how to help
Have clear ways to tell people	Makes sure the right people know quickly

8. Develop a Post-Incident Analysis Process

After dealing with a cyber attack, it's important to look back at what happened. This helps you understand the problem and stop it from happening again. Here's how to do this:

Create a No-Blame Environment

When looking at what happened, don't try to find someone to blame. This helps people share information without worry. When everyone feels safe to talk, you can:

Find out why the problem really happened
Make changes to stop it from happening again

Check Every Report

Look at every report about what happened after an attack. This helps you:

Fix any leftover problems
Get ideas on how to do better next time
Finish the report

Make a Timeline

Put together a list of what happened and when. This should include:

Event	Why It's Important
First alert or ticket	Shows when the problem was first noticed
First message sent out	Tells when people were told about the problem
Updates to status page	Shows how information was shared

A good timeline helps you see where you can do better next time.

9. Link Your Incident Response Plan with Other Emergency Plans

It's important to connect your incident response plan with your business continuity and disaster recovery plans. This helps your company handle big problems better and get back to work faster.

Why Linking Plans Matters

When you connect these plans, you:

React quickly to security issues
